\"en\", \"value\": \"AV:L - Both halves of the race are driven by `sendmsg()` on a local NETLINK_RDMA socket (`rdma_nl_rcv_msg` \\u2192 `nldev_newlink` and `nldev_set_doit`); no remote or adjacent peer data reaches the vulnerable code.\\nAC:L - The attacker owns both sides of the race, looping RDMA_NLDEV_CMD_NEWLINK (rxe/siw link add, which ends in `ib_device_notify_register()`) in one thread against RDMA_NLDEV_CMD_SET rename in another; the device is already in the `devices` xarray and reachable by index before the unprotected notify runs, and syzkaller reproduced it.\\nPR:L - The gate is `netlink_capable(skb, CAP_NET_ADMIN)` against `init_user_ns`, so it is not obtainable via `unshare -Urn`, but CAP_NET_ADMIN in the initial user namespace is routinely delegated to non-root container workloads (Docker/K8s RDMA and SR-IOV network plugins commonly run `--cap-add=NET_ADMIN` without user namespaces), so this is scored as a low-privileged principal rather than real host root.\\nUI:N - The attacker issues both the device registration and the concurrent rename itself over netlink; no victim action of any kind is required.\\nS:U - The use-after-free is on kernel slab memory and its consequences remain within the kernel\u0027s own security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\\nC:H - `nla_put_string()` runs `strlen()` and `memcpy()` over the freed `kobj-\u003ename` chunk and the result is `rdma_nl_multicast()`ed to RDMA_NL_GROUP_NOTIFY, a group any unprivileged process may bind because the RDMA netlink socket sets `NL_CFG_F_NONROOT_RECV` \\u2014 reallocated kernel heap contents, plus an unbounded out-of-bounds read past the freed chunk when no NUL follows, are disclosed straight to userspace.\\nI:H - This is a slab use-after-free where the attacker can spray the freed kmalloc chunk and control the bytes the kernel then consumes and emits; per UAF-class scoring the reallocation primitive is treated as exploitable for kernel state corruption, and the forged device name additionally steers RDMA monitor tooling in userspace onto the wrong device.\\nA:H - The `strlen`/`memcpy` over freed memory is a KASAN slab-use-after-free read that oopses when the backing page has been returned or under KFENCE/page poisoning, and on `panic_on_warn` systems the KASAN report itself panics the host.\"}]}], \"affected\": [{\"repo\":

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
